Digital BW, The Print

Greetings

     This is my first post to the group.  Most of the discussions 
seems to be about printers and paper.  Does anyone have any advice on 
which camera to use for B&W photography.  Does it matter?  I mean, 
are there camers that have a function for B&W?  If so, is it just as 
well do take color shots and turn them into B&W on a computer?

    I just got a Sony DSC-P10 Cyber-shot for Christmas, and I'm 
wondering if there is anything out there for under $600 that is 
better for low-light without a flash and B&W?

Any advice would be appreciated.

Jeff
